This visualization presents a pie chart of Stranger Things character popularity, with data aggregated from a 2025 CSV dataset. It uses D3.js v7 to render the full-circle chart as SVG, with slices colored via `d3.scaleOrdinal` and `d3.schemeTableau10`. The code groups characters with less than 2% of total popularity points into an "Other" category, and labels slices with percentages where they exceed 3%. A separate HTML legend lists each character’s name, percentage, and raw point value.
